Ubuntu Security Notice USN-3690-1
June 20, 2018

amd64-microcode update
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

The system could be made to expose sensitive information.

Software Description:
- amd64-microcode: Processor microcode firmware for AMD CPUs

Details:

Jann Horn discovered that microprocessors utilizing speculative execution
and branch prediction may allow unauthorized memory reads via sidechannel
attacks. This flaw is known as Spectre. A local attacker could use this to
expose sensitive information, including kernel memory.

This update provides the microcode updates for AMD 17H family
processors required for the corresponding Linux kernel updates.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
  amd64-microcode                 3.20180524.1~ubuntu0.18.04.1

Ubuntu 17.10:
  amd64-microcode                 3.20180524.1~ubuntu0.17.10.1

Ubuntu 16.04 LTS:
  amd64-microcode                 3.20180524.1~ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  amd64-microcode                 3.20180524.1~ubuntu0.14.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
